Dear Sir:

A member of your staff telephoned the Authority to request additional information regarding masonry wall design at our FitzPatrick Plant.

our response.

Attached to this letter is a summary of those questions and If you have any further questions, pleaca contact Mr. J.A. Gray, Jr.

Attachment to OvN-83-06 POWER AUTHORITY OF THE STATE OF NEW YORK JAMES A. FITZPATRICK NUCLEAR POWER PLANT Response to Oral Request for Additional Information Regarding Masonry Wall Design, IE Bulletin No. 80-11 QUESTION 1: Identify those masonry walls evaluated by the Power Authority which have stress factors greater than those specif'.ed by the NRC's Structural Engineering Branch for extreme environmental conditions - (1.5 for tension parallel to bed joint and 1.3 for tension normal to the bed joint and masonry shear) .

RESPONSE 1: Two masonry walls have calculated stress factors greater than 1.50 for tension parallel to the bed joint.

a. Wall No. PH-255-3 (Pumphouse) , stress factor:

1.57.

b. Wall No. EB-272-15 (Turbine Building) , stress factor: 1.65. This wall was formerly considered as wall Nos. EB-272-13. (see Ref. 1)

The only wall with a stress factor greater than 1.30 for tension normal to the bed joint is Wall No.

EB-272-11 (Turbine Building), with a stress factor of 1.32. This is only slightly over the 1.30 criteria. Although the Authority was told during discussions with NRC staff members that this wall could be omitted from this list, we have included it for completeness.

QUESTION 2: Identify the location of those masonry walls with stress factors greater than 1.30. Identify structures, systems and components in their immediate vicinity.

RESPONSE 2: This information was previously supplied to the NRC in a report entitled "IE Bulletin No. 80-11, (60 day Response) . " This report was submitted as an attachment to Refernece 1.

i l

/ . .

QUESTION 3: Provide jdstification for those masonry walls with stress factors in excess of 1.30.

RESPONSE 3: Refer to the Au .ority's response to to Question 5 of Reference 2 for a discussion of allowable stress factors.
